The nation's capital entered mandatory curfew at 6 p.m. yesterday following a never-before-seen siege on the US Capitol Building that saw rioters break into the legislature during a joint session of Congress and clash with federal police who attempted to hold them back. Protests surrounding the certification of the Electoral College quickly turned violent as supporters of President Donald Trump descended upon Congress following the president's speech near the White House.

Law enforcement agencies from around the capital including the United States Secret Service and Federal Bureau of Investigation arrived at the Capitol after the riots were underway. The neighboring states of Maryland and Virginia also sent National Guard and state police across the border into the District to assist. 

The siege left at least one person dead by gunshot, law enforcement officials told NBC News and the Washington Post, and three others dead by "medical emergencies," as Washington Police Chief Robert Contee said and NBC News reported, as well as others injured. Law enforcement officials guarding the congressional chambers drew their weapons as rioters attempted to enter while pepper spray and tear gas were deployed. 

The Capitol itself also sustained damage as rioters broke windows and climbed scaffolding to gain entry. Speaker of the House Nancy Pelosi's office was also vandalized. 

Here's what the US Capitol Building looked like after rioters failed to overturn the 2020 US election.

Protests quickly escalated to riots and pepper spray was used to block access into the building. The orange liquid now stains the Capitol walls.

What appeared to be a flash-bang grenade, which reporters witnessed police using earlier in the day, also illuminated the Capitol's iconic facade. This is also where incoming presidents are sworn into office.
